GRAIN- DRILL.

SPECIFICATION forming part of Letters Patent No. 308,899, dated December9, 1884.

Application filed Juneii), 18S-1. (No model.)

Y simultaneously distribute grain and fertilizing materials, the twobeing discharged in a mingled current as the machine. advances acrossthe iield; and it consists in certain improvements in the constructionof the receiving` and discharging apparatus, as will be hereinafterexplained.

In the drawings, Figure lis avertical transverse section through thegrain and fertilizer receptacles `and the discharging passages which areconnected therewith. Fig. 2 is a rear elevation showing a fragment ofthe supporting-bar and two ofthe receptacles mounted thereon. Fig. 3 isa perspective plan view showing the manner in which thedischarging-tubes are supported. Fig. et is a detail showing the sameparts in vertical section.

A is the grain-receptacle, and A is the fertilizer-receptacle, the twobeing separated by the diaphragm or partition a.

B is the chute leading from the grain-receptacle, and B is the chuteleading from the fertilizer-receptacle, b being a partition whichseparates one from the other. The rear chute, B', is provided at its topwith an outwardlyprojecting Bange, b', to receive screws or bolts, bywhich it is secured to the bottom of the receptacle A.

C and C are respectively the front and rear feed-rollers of the drill.The upper front portion, b, of the grain-chute B terminates at a pointin close proximity to the front roller, C, as seen in Fig. l. At theirlower extremity the chutes B and B extend a suitable distance into theupper flaring portion of a hopper, D, which terminates downwardly in ashort discharge-pipe, which is fitted into an orifice in thesupporting-bar E, through which itprojects for a short distance into theupper iiaring extremity of the discharging-tube F, the

upper hopper-shaped portion, f, of which is loosely received within acorrespondingly iiaring ring or collar, H. The ring H is pro vided uponIits exterior face with two short oppositely-placed trunnion-like ears orjournals, h 7L, which are received within bearings h h, formed in thedepending portions of angular supports G G, the horizontal port-ions ofwhich are secured by 'screws or bolts g to the under surface of thesupporting-bar E. Grain being supplied to the receptacle A passesthrough the discharge-oriiice c in the bottom thereof and falls into thespace between the rollers C and C', by which it is suitably distributedand carried downwardly. The upper front extremity or scraper, b, of thechute B being, as already stated, almost in contact with the roller C,serves as the roller revolves to detach from theface of theroller anykernels of grain or any other substancewhich by any chance may adherethereto, and the roller is thus kept in suitable condition to do itsmost effective work in distributing and discharging the grain. Thefertilizing, material falls through the dischargeorilice a of thereceptacle A', and as will be seen is kept separate from the grain untilboth have passed from their respective chutes into the hopper D. Theinclination of the front portion of the chute B is such that the grainas it descends is given a direction and an impulse which carry it welltoward the rear inner portion of the tubular part of the hopper D, whilethe fertilizing material is given a direction which causes it to strikethe grain-current substantially at a right angle thereto, and the twocurrents, each falling athwart the other, are thus thoroughly commingled. As will be seen, the lower portion of the two chutesB and B iscut away or made shorter toward the rear thereof, and, besides, t-he twoare placed slightly eccentrically to and toward the front of the hopperD. rlhis construction permits observation, as indicated by the arrow inFig. l, of the operation of commingling the two distinct materials asthey unite in passing from their respective chutes.

In the practical use of this class of devices it is found that a currentof air which constantly risesthrough the discharge-tube tends. to retardsomewhat the downward ilow of the grain and the fertilizer. To avoid sofar as IOC) practicable the effect of this upward flow of air, I placethe top ofthe Haring portionf of the tube F a short distance below thesupporting-bar E, so that through the annular opening f thus providedthc retardingcurrent may find lateral escape.

rlhe discharge-tube F being composed of rubber or other flexiblematerial, the flaring portion f of the same is readily tted into orremoved from its seat in the ring H by being rst compressed bythe handsand'thcn passed the hopper-shaped portionf of the dischargel tube beingreadily lifted from its bearing, and thus made horizontally adjustableat will, to avoid excessive wear upon any particular porY tion thereof.

Having thus described my invention, what I claim is p l. Thecombination, with the roller C, of the scraper b at the upper frontportion of the grain-chute B.

2. lThe combination, with the fertilizerchute B', of the grain-chute B,provided with the scraper b.

3. The combination, with Ythe roller C, of

the roller C and the scraper b.

4. The combination, with the hopper D, of the chutes B and B',projecting into such hopper, each of the chutes being at its lower eX-tremity inclined upwardly from the front t0- ward the rear, asdescribed.

5. The combination, with the hopper D, of

and projecting below such supporting-bar, and,

the discharge-tube F, supported by its flaring top f in the pivotcdcollar or seat H, such haring top being placed a short distance belowthe supporting Y bar, as and for the purposesV set forth.

7. The combination, with the supportingbar E, of the angular supports GG, secured to such bar and having bearings h h', and the supporting-ringH, havingjournals h 7L,where by it is supported in such bearings.

S. The combination, with the supportingbar E, ol' the angular supports GG, the pivoted or journaled seat H, and the dischargetube F. havingl'laring portion j".

S). The combination, with the supportingbar E, ot the hopper D, thejournaled ring or seat H, the compressible discharge-tube F, and theannular discharge-openingf, which encircles the lower portion of thehopper D.

l0. The combination, with the grain-chute B, having at its upperextremity the roller C and the scraper b, of the hopper D and theiiexible pivotally-supported tube F.

1l. A iiexible discharge tube for graindrills, which ispivotally-supported and which is axially adjustable in its seat.

In testimony that I am the inventor of the above-described improvementsin wheatdrills I hereto subscribe my name.
